Site Information and Foundation Specifications
Overview
The reinforced concrete slab foundation or reinforced concrete pier foundation must be constructed in
accordance with supplied drawings and specifications. Both foundation systems are dimensionally
identical at contact points with the scale. Either the slab or pier foundation may be used with the SR or EZ
series scales, depending on local climate and soil conditions.
Per NTEP specifications, level concrete approaches at least 10' in length are required at entrance and exit
to the scale. Necessary ramps from approaches to existing grade may be concrete, asphalt, gravel or other
suitable surface. Contact your State Weights and Measures Department for site-specific requirements.
Soil Bearing Capacity
Footings must bear on undisturbed soil or compacted granular fill per specifications with a minimum
bearing capacity of 3000 psf. It is the responsibility of the concrete contractor to verify this value. If soil
at the bottom of a footing is of questionable value, notify the local project engineer.
Deviation from Published Specifications
Foundation drawings from Rice Lake Weighing Systems include all dimensions, steel reinforcement
details, and concrete mix specifications to complete the foundation construction. Estimated material
quantities are also included on the drawings. Any deviations from the published drawings must be ap-
proved in writing from Rice Lake Weighing Systems.
Concrete Sampling
A schedule of concrete sampling sets taken in approved cylinders per ASTM C31, C39, and C172 is
detailed on the drawings. A set of cylinders is to be broken at 7 days and 28 days by an approved soil
testing facility, and a third set is to be stored by the concrete contractor and maintained in good condition.
